For iPad

Shock-absorbing double-reinforced corners stabilize and cushion your iPad in the event of impact. Finally, full access is available to buttons and ports while you work or play.

Even when it?s in a hard or soft case, you?ll travel light with this slim cross-body bag for the iPad. Two interior pockets and one exterior pocket store keys, cables, a charger, and accessories. There?s also a convenient access port for headphones and grips on the bottom of the bag for easy removal of the iPad.
